Struct trust_graph::TrustGraph

pub struct TrustGraph { /* fields omitted */ }

Graph to efficiently calculate weights of certificates and get chains of certificates. TODO serialization/deserialization TODO export a certificate from graph

Implementations

impl TrustGraph

pub fn new(root_weights: Vec<(PublicKey, u32)>) -> Self

pub fn add_root_weights<P: Into<PublicKeyHashable>>(
    &mut self,
    weights: Vec<(P, u32)>
)

Insert new root weights

pub fn get(&self, pk: PublicKey) -> Option<&TrustNode>

Get trust by public key

pub fn add<C>(&mut self, cert: C, cur_time: Duration) -> Result<(), String> where
    C: Borrow<Certificate>, 

Certificate is a chain of trusts, add this chain to graph

pub fn weight<P>(&self, pk: P) -> Option<u32> where
    P: Borrow<PublicKey>, 

Get the maximum weight of trust for one public key.

pub fn certificates_weight<C, I>(&self, certs: I) -> Option<u32> where
    C: Borrow<Certificate>,
    I: IntoIterator<Item = C>, 

Calculate weight from given certificates Returns None if there is no such public key or some trust between this key and a root key is revoked. TODO handle non-direct revocations

pub fn get_all_certs<P>(
    &self,
    issued_for: P,
    roots: &[PublicKey]
) -> Vec<Certificate> where
    P: Borrow<PublicKey>, 

Get all possible certificates where issued_for will be the last element of the chain and one of the destinations is the root of this chain.

pub fn revoke(&mut self, revoke: Revoke) -> Result<(), String>

Mark public key as revoked.

Trait Implementations

impl Debug for TrustGraph

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TrustGraph

pub fn default() -> TrustGraph

Returns the "default value" for a type.
